Biography

I am a machine learning researcher with research interests in hypothesis testing and trustworthy machine learning. My long-term goal is to develop trustworthy intelligent systems that can learn reliable knowledge from massive related but different domains automatically. Researching hypothesis testing and trustworthy machine learning is the first step for achieving my long-term goal.

I am currently a Lecturer (Assistant Professor) at Decision Systems and e-Service Intelligence (DeSI) Lab, Australian Artificial Intelligence Institute (AAII), University of Technology Sydney (UTS), Australia. I am also a Visiting Scientist at RIKEN-AIP, Japan. I was the recipient of the Australian Laureate postdoctoral fellowship. I received my Ph.D. degree in computer science at UTS-AAII in 2020, advised by Dist. Prof. Jie Lu and Prof. Guangquan Zhang.

I was a research intern at the RIKEN-AIP, working on the robust domain adaptation project with Prof. Masashi Sugiyama, Dr. Gang Niu and Dr. Bo Han. I visited Gatsby Computational Neuroscience Unit at UCL and worked on the hypothesis testing project with Prof. Arthur Gretton, Dr. Danica J. Sutherland and Dr. Wenkai Xu.

I have served as a senior program committee (SPC) member for ECAI and program committee (PC) members for NeurIPS, ICML, ICLR, AISTATS, ACML, AAAI, IJCAI, CIKM, ECAI and so on. I also serve as reviewers for many academic journals, such as IEEE-TPAMI, IEEE-TNNLS, IEEE-TFS, PR, AMM and so on. I received the Outstanding Reviewer Award of NeurIPS (2021), the Outstanding Reviewer Award of ICLR (2021), the UTS-FEIT HDR Research Excellence Award (2019), the Best Student Paper Award of FUZZ-IEEE (2019) and the UTS Research Publication Award (2018).

Research Interests

My research interests lie in hypothesis testing and trustworthy machine learning. Specifically, my current research work center around three major topics:

• Two-sample Testing: Measuring the discrepancy between two data distributions, a fundamental problem in machine learning and statistics.

• Transfer Learning: Leveraging the knowledge from domains with abundant labels (i.e., source domains)/pre-trained models (i.e., source models) to complete classification/clustering tasks in an unlabeled domain (i.e., target domain).

• Defending against Adversarial Attacks: Detecting adversarial attacks (i.e., adversarial attack detection); Training a robust model against future adversarial attacks (i.e., adversarial training).
